Even if you have TTS-1 already installed when loading a midi in the Cakewalk it will not load TTS-1 with the Midi. So no midi player except you go in and assign everything manually. A real pain.
Some plugins behave differently if you unclick enhanced display option under the Plugin Properties but not all. Breverb does change to large screen trying other.
TTS-1 was great to get a midi up and playing quickly. If you had midi files associated with cakewalk once clicked upon the midi opened and applied TTS-1 to all tracks and later you could use other synths if you wanted. I'm ok as I have it from the old days.
